Radiocarbon ages, whole-rock geochemical data, and pumice density measurements for the Sacarosa tephra-fall deposit, Misti volcano, southern Peru
These data are derived from the Pleistocene Sacarosa tephra-fall deposit (TFD) which erupted from Misti volcano, Arequipa, southern Peru. The deposit represents a major eruption of Misti and these data are used to characterize the deposit. The radiocarbon ages are from units bracketing the Sacarosa TFD and constrain its eruption age. Whole-rock major and trace element concentrations for Sacarosa pumice were determined by X-ray flourescence and inductively coupled plasma mass spectrometry. Density was measured for 89 pumice from six bulk samples of the Sacarosa TFD. These data are provided as part of an effort to characterize the Sacarosa TFD and determine its eruption age.
